Thanks for the ideas. I am starting with a second hard drive and the
dd command as Derek said and I am going to try to recreate how I go
into this mess.  Understanding, at his point, is more valuable than
the little bit of data since my last last backup.

To partially answer some questions:
The disk started with Windows 7 and I installed Ubuntu 10.10 with dual
boot.  So the partition utility is the one used during the Ubuntu
install.  Also, I vaguely remember a question about encryption during
that process.  I can't say for sure whether the partition or just the
home directory was encrypted.
Also, I'm not sure where the boot record was.

If possible, I will reinstall everything and then find those answers.
At, the speed this dd is going, I have some free time to do more research.
...John
